 Foreword  
 
This Draft Tanzania Standard  has been prepared in orde r to guide manufacturers of bed spreads meant 
for household, public and commercial uses.  
 
In the preparation of this Draft Tanzania Standard  assistance  was derived from;  
 
Company specifications  established by  Tanzania n textile industries  
 
ASTM D4037 − 02 (Reapproved 2013 ), Standard  performance specification for woven, knitted, 
or flocked bedspread fabrics . 
 
SANS – 1261 – 1: 2008 Performance r equirements for retail textiles Part 1: Household piece -
goods and articles  
 
In reporting the result of a test made in accordance with this Draft Tanzania Standard , if the final value 
observed or calculated is to be rounded off, it shall be done in accordance with TZS 4 (see clause 2).

5. PACKING AND LABELLING  
 
5.1 Packing  
 
5.1.1  Pieces  
 
Each piece or pair of bed spread(s) shall be neatly and securely wrapped in polythene wrappers to 
prevent contamination or damage.  
 
 
5.1.2  Bulk  
    
5 
 The neatly and securely wrapped pieces shall be packed in cartons or boxes. A bulk container shall 
consist of only the same type, dimensions and style of bedspread(s).  
 
5.2 Labelling  
 
 
5.2.1  Care labelling  
Each piece pair of bed spread(s) shall bear a sewn -in care label showing symbols and /or words for 
caring process as indicated in TZS 691.  
 
6. MARKING  
 
6.1 Pieces  
Each pack and/or pair of bedspread(s) shall have a label securely attached bearing the following 
information:  
 
a) Manufacturer's name or registered trade mark;  
b) Fabric composition;  
c) Size of the bed spread(s) in cm;  
d) Care instructions and  
e) Country of origin.  
 
6.2 Bulk containers  
 
Each bulk container shall have a label securely attached, bearing the following information:   
 
a) Name and full address of manufacturer;  
b) Registered trade mark;  
c) Type of bed spread(s);  
d) Size of the bed spread(s) in cm;  
e) Fabric composition;  
f) Quantity of pieces;  
g) Batch/lot number and  
h) Country of origin.  
 
7. SAMPLING  
 
7.1 Lots  
 
7.1.1  The quantity of bed spreads of the same type and quality delivered to one buyer against one 
dispatch note shall constitute a lot.  
 
7.1.2  The conformity of the lot to the requirements of this Draft Tanzania Standard  shall be 
determined on the basis of tests carried out on the sampl es selected from the lot .  
 
7.1.3  The number of pieces to be selected at random from a lot shall be in accordance with the 
second column of Table 3. These pieces shall be selected from at least 10 % of the bales, an 
equal number of pieces, as far as possible, be ing selected at  random from each bale.

6.3 Criteria for conformity  
 
a) From the observed values of breaking load tests in respect of each piece in the test sample, the 
average breaking load is calculated.  
b) From all such average values, the grand average ( ) and the average range R1 is calculated and the 
value of the expression   – 0.4R1 is found to be greater than or equal to the specified value (≥).  
c) From the observed values of shrinkage the ave rage  and the range R are calculated and the value 
of the expression   +0.4R is less than or equal to the specified value (≤).  
 
NOTES –  
 
1. Average ( ) is the value obtained by dividing the sum of observed values by the number of tests.  
2. Range ( R) is the difference between the maximum and the minimum in a set of observed values.
